> Humans are ... antisocial
The well-established facts are that Homo sapiens and related species are 100% social animals; we live in groups and do not survive alone. We're not like wolves or bears; chimpanzees live in groups, not alone in the jungle. Our means of living, surviving, and thriving are all built for doing it only in groups, including empathy, cooperation, and altruism - universal human traits. (We even like to talk with strangers from unknown locations whom we'll never meet!) Isolated humans suffer severe mental breakdowns, such as in solitary confinement (which is considered torture).
Why do people like to argue for social nihilism and isolation? It's hard to name any respected leader or scholar who has claimed it - among leaders, even the worst murderers claim to do it for social good. For some people arguing nihilism/isolation may be externalizing fear or trauma and especially a feeling of isolation, a very human and social thing way to process those things (though there are healthy ways). Sometimes people want to seem or feel more serious or stronger by saying something more dangerous or dark.
Regardless, as I said, our discussion isn't idle speculation. We are actors; our words have impact; we are responsible for the impact we have on the people around us, our communities, our world. Again, who will we be?
I don't want to speculate or cross bounderies, but if you feel that dark and isolated I have good, but challenging news: Despite what some loud voices of the time say - people relentlessly seeking power and saying anything, no matter how absurd, to get it - we are social, humans have good instincts (and bad ones), and we thrive by embracing the good ones.
Freedom and democracy trust in our good instincts (which must be why its enemies promote nihilism), and have produced societies unmatched in freedom, justice, prosperity, and safety. Part of that is the ability to cooperate on a large scale - a consequence of building on good instincts: look at NATO, an alliance held together by its values, by trust and cooperation, and the most powerful military force in the world by far.
